Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional shut-off devices use complex mechanical components for assembly, then the locking and sealing functions are reliable, but the assembly process becomes cumbersome and maintenance complexity increases
Solution Approach 1:
The closure element is divided into separate functional components: a closure body with integrated locking element, and a membrane sealing component. This segmentation allows each part to be optimized independently while simplifying the overall assembly process, as the closure element can be installed as a single unit without requiring complex mechanical fastening components.
Solution Approach 2:
The locking element is merged with the closure body as an integrated component rather than a separate mechanical part. This merging eliminates the need for additional locking mechanisms, screws, or clips, thereby reducing device complexity while maintaining reliable locking function through the geometric design of the integrated element.
2Reliability
If additional mechanical components are used for assembly, then the locking mechanism is secure, but the assembly efficiency decreases and maintenance becomes more difficult
Solution Approach 1:
The locking element is pre-formed as an integral part of the closure body during manufacturing. This preliminary action ensures the locking geometry is precisely formed without requiring additional assembly steps, thereby improving assembly efficiency while maintaining secure locking through the pre-configured geometric features.
3Reliability
If complex mechanical components are used for closure element attachment, then the connection is secure, but the maintenance and replacement process becomes cumbersome
Solution Approach 1:
The locking function is extracted from complex mechanical components and realized through the geometric design of the integrated locking element on the closure body. This extraction allows the closure element to be removed and replaced by simply withdrawing it from the valve body, making maintenance straightforward while maintaining secure connection through the engineered geometry of the locking features.

AI summary
An intermediate piece (120) for a shut-off device, in particular a diaphragm valve, for fluids is described. A pressure piece (48) can be arranged in the intermediate piece (120). The pressure piece (48) has at least two locking slides for locking a locking element of a closure element. The intermediate piece (120) has a cylinder (122) in which the pressure piece (48) can be guided axially. The intermediate piece (120) has a recess (132) which is arranged such that, in an assembly position of the pressure piece (48), the locking slides move into the recess (132) and thus release the locking element.
